The crystals on this fine specimen from the Rogerley Mine are sharp, gemmy, and transparent, and cover most of the surface of the matrix. Of course the color is outstanding: it is the characteristic Rogerley Mine highly saturated bluish-green under indoor lighting, with excellent fluorescence under LW UV and some mild daylight fluorescent when seen in daylight. The crystals (to 10mm from tip-to-tip) are penetrating twins, and are exceptionally shiny and lustrous.  This is a highly aesthetic fluorite specimen from one of the best pockets found at the Rogerley Mine.
